How does the thermal expansion of eucalyptus compare to teak in outdoor ottoman joints?

When selecting wood for outdoor ottomans, understanding thermal expansion is crucial for durability. Eucalyptus and teak are popular choices, but their thermal expansion properties differ significantly.

Eucalyptus, a fast-growing hardwood, has a higher coefficient of thermal expansion compared to teak. This means eucalyptus joints may expand and contract more with temperature fluctuations, potentially leading to looser fittings over time. Teak, known for its stability and natural oils, exhibits lower thermal expansion, making it more resistant to joint movement in outdoor conditions.

For outdoor ottomans exposed to sun and rain, teak's superior dimensional stability often makes it the preferred choice. However, properly treated eucalyptus with sealed joints can still perform well in moderate climates. Consider your local temperature swings when choosing between these two woods for long-lasting outdoor furniture.
